39510-74-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39510-74-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,5,1 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 39510-74:
(7*3)+(6*9)+(5*5)+(4*1)+(3*0)+(2*7)+(1*4)=122
122 % 10 = 2
So 39510-74-2 is a valid CAS Registry Number.

Zinc acetate-mediated regioselective N-acylation of 1,3-disubstituted selenoureas

Li, Xue,Gan, Bin,Peng, Zhixiang,Mi, Zhisheng,Xie, Yuanyuan

, p. 251 - 254 (2018/06/27)

N-acetylureas were synthesised regioselectively from 1,3-disubstituted selenoureas and zinc acetate. Regioselectivity was dependent on the pKa of the amine attached to the selenourea and occurred towards the amine with the lower pKa. The approach provided a simple, mild and efficient way to construct various N-acetylureas regioselectively in moderate to good yields (53-88%). A plausible mechanism was proposed for the formation of N-acetylureas.

Hypervalent iodine(III)-mediated regioselective N-acylation of 1,3-disubstituted thioureas

Singh,Ghosh, Harisadhan,Murru, Siva,Patel, Bhisma K.

, p. 2924 - 2927 (2008/09/19)

(Chemical Equation Presented) Reaction of asymmetrical 1,3-disubstituted thioureas with diacetoxyiodobenzene (DIB) produces regioselectively N-acetylurea in shorter time. Regioselectivity is dependent on the pKa's of the amine attached to the t

Oxidative rearrangement and cyclisation of N-substituted amidines using iodine(III) reagents and the influence of leaving group on mode of reaction

Ramsden, Christopher A.,Rose, Helen L.

, p. 2319 - 2327 (2007/10/03)

The products of reaction of N-substituted amidines 5 with hypervalent iodine reagents such as (diacetoxyiodo)benzene (DAIB), bis(trifluoroacetoxy)iodobenzene (BFIB) and [methoxy(tosyloxy)-iodo]benzene (MTIB) are determined by the reagent, the amidine substituents and the reaction temperature. C-Alkyl-N-arylamidines 5a-d cyclise in high yield giving benzimidazoles 6 but C,N-dialkyl- and C,N-diaryl-amidines 5e-l rearrange to give products derived from an intermediate carbodiimide. Use of N2-phenylfuran-2-carboximidamide 5j leads to N-(2-furyl)acetamide 15 in good yield, illustrating a convenient route to stable derivatives of highly unstable 2-aminofuran. The rearrangement of C,N-diarylamidines on reaction with DAIB contrasts with the observed formation of benzimidazole when the same precursors are treated with lead tetraacetate (LTA). Evidence is presented to support the view that the mode of reaction is determined by the nature of the leaving group in an imide intermediate 19: very good leaving groups [e.g. PhI, N2, AgCl and PhSO2O- (aq.)] appear to favour rearrangement whereas poorer leaving groups [e.g. Cl-, Me2S, Me3N and PhSO2O- (non-aq.)] favour cyclo-α-elimination.
